WebbThermometric Titration: The elementary statement, that every chemical reaction is accompanied by a change in energy, is precisely what constitutes the basis of thermometric titration. During endothermic reactions, energy is absorbed and a temperature drop is observed. The opposite is true for exothermic reactions where … WebbFor an acid-base reaction the equivalence point is where the moles of acid and the moles of base would neutralize each other according to the chemical reaction. This does not necessarily imply a 1:1 molar ratio of acid:base, merely that the ratio is the same as in the chemical reaction. It can be found by means of an indicator, for example ...
